Thanks! I had read the fact sheet, I just hadn't seen anything about them cohabitating, except when they were feeling frisky. :-) And I will get them a larger tank, or maybe just a second 20 gallon. On that point, do you think they care one way or another whether they live alone or not? (Not to delve too far into the amphibian mind...)

Also one more question. It says to give them a sandy substrate. Is that preferable to husks/bark? (I had read that elsewhere, so I picked up a bag of Repti-Bark (fir bark).) If so, are we talking straight sand? Some kind of mix?

Thanks again! :-)
